`{:("Column I",,"Column II"),("A) Rivet Popper hypothesis",(i),"Paul Ehrlich"),("B) Long-term ecosystem
experiments using outdoor plots",(ii),"David Tilman"),("C) Species-area relationships",(iii),"Alexander von
Humboldt"):}`
(a) A-(iii), B-(i), C-(ii)
(b) A-(i), (ii), C-(iii)
(c) A-(i), B-(iii), C-(ii)
(d) A-(ii), B-(iii), C-(i)

Options

A. A-(iii), B-(i), C-(ii)
B. A-(i), (ii), C-(iii)
C. A-(i), B-(iii), C-(ii)
D. A-(ii), B-(iii), C-(i)

Answer

To solve the matching question, we will analyze each item in Column I and find its corresponding match in Column II based on the information provided.

### Step-by-Step Solution:

1. **Identify the Rivet Popper Hypothesis**:
- The Rivet Popper Hypothesis was proposed by **Paul Ehrlich**. This hypothesis suggests that every species in an ecosystem plays a crucial role, similar to rivets in an airplane. Removing a species (or rivet) can weaken the entire ecosystem.
- **Match**: A) Rivet Popper Hypothesis → (i) Paul Ehrlich

2. **Identify Long-term Ecosystem Experiments**:
- Long-term ecosystem experiments using outdoor plots were conducted by **David Tilman**. His work focused on understanding the effects of biodiversity on ecosystem functioning.
- **Match**: B) Long-term ecosystem experiments → (ii) David Tilman

3. **Identify Species-Area Relationships**:
- The Species-Area Relationship was studied by **Alexander von Humboldt**. He established a mathematical relationship that describes how the number of species increases with the area surveyed.
- **Match**: C) Species-area relationships → (iii) Alexander von Humboldt

4. **Compile the Matches**:
- A matches with (i)
- B matches with (ii)
- C matches with (iii)

5. **Select the Correct Option**:
- The matches are:
- A - (i) Paul Ehrlich
- B - (ii) David Tilman
- C - (iii) Alexander von Humboldt
- Therefore, the correct option is **(b) A-(i), B-(ii), C-(iii)**.

### Final Answer:
The correct option is **(b) A-(i), B-(ii), C-(iii)**.
